Vortex Racing has been the choice of professional race teams worldwide since 1995. Their CAT5 series sprockets undergo a meticulous manufacturing process where the aluminum is color anodized before precision machining, creating a trick appearance with exposed silver highlights on the sweeps, mud grooves, and teeth. The lightweight design reduces rotating mass and helps transfer more power to the pavement, while the specially formulated 7075 aluminum alloy ensures durability under racing conditions.
